I'm looking to deploy what is effectively user segmentation of my data. I  
have a moderately high number of users (say 10K), and I want each to be  
able to query an alias that is their own.

This is not meant as a security measure, but as a backstop. Developers on  
my team will not try to guess another user's index name, but I don't want  
to count on every query remembering to add user filtering.

From the docs

* * *

## curl -XPOST '[http://localhost:9200/\_aliases](http://localhost:9200/_aliases)' -d ' { "actions" : [{ "add" : { "index" : "test1", "alias" : "alias2", "filter" : { "term" : { "user" : "kimchy" } } } }] }

Is what I want except that I want the term == alias so

* * *

## curl -XPOST '[http://localhost:9200/](http://localhost:9200/)_aliases' -d ' { "actions" : [{ "add" : { "index" : "test1", "alias" : "alias_[X]", "filter" : { "term" : { "user" : [X] } } } } ] }

then

[http://localhost:9200/alias\_bob/\_search](http://localhost:9200/alias_bob/_search)

would let you search only bob's data

Does ES have anything like this? Is it coming?

Thanks,  
John
